RAILWAY CATTLE-GUARD.

SPECIFICATION formingpart of Letters Patent No. 275,333, dated April 3, 1883.

Application filed July 24, 1882. (No model.)

To all whom "it may concern:

Be it known'that we, BENJAMIN F. DILLON and ALBERT GA'RTNER, of Savannah, in the county of Ohatham and State of Georgia, have invented a new and Improved Railway Cattle- Guard and we do hereby declare that the followingis a full, clear, and exact description of the same.

This invention is an improvement in guards for railways for preventing cattle straying on the latter or passing from or into an inclosure at points where the railway enters and leaves it, whereby the use of the customary pits as now constructed by railroads may be dispensed with.

The construction and combination of parts are as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of our improved cattleguard as applied in actual use, and Fig.2 is a cross-section of the same. Fig. 3 is a perspective View of aportion of one of the spiked rollers and the metal cap therefor.

The guard is formed by means of a series of spiked rollers A, arranged preferably parallel with the rails B, and journaled in flanged plates 0, which are attached to the cross-ties D. Said plates 0 are oblong, and provided with holes to receive the journals a of said rollers A, and with horizontal base-flanges I), through which screws are inserted into the ties D for securing the plates firmly in place. On the ends of the rollers are fitted central caps, 0, having the journals or gudgeons a cast in one piece with them. The pointed iron spikes are arranged spirally or in zigzag relation around the rollers A, and project radially therefrom. The latter are placed a few inches apart,

and occupy the space between the railsB and also the lateral spaces between the rails and posts E of the fence, on either side of the track. The space between the rollers should preferably not be sufficient to allow a bullocks foot to pass down between them, although, in case this should happen, the leg of thebullock is not liable to be injured, since the rollers will not pinch it nor prevent its withdrawal, as do those rollers which are cruciform in cross-section or whose transverse diameters are of unequal length. 7

\Ve are aware that cattle-guards have been formed of rotatable bars; but the latter were constructed of metal and groo'vedlengthwise, and hence cruciform in cross section. They are therefore dangerous in use, for, when a bullock attempts to cross the guard the application of his weight will cause them to rotate and pinch his legs so severely as to be liable to break them, and in most cases it would be impossible for the bullock to extricate his legs, even if not seriously injured. In our invention the feet and not the legs are pinched, and hence injury is not liable to result.

What we claim is- The improved railway cattle guard formed of a series of rollers arranged parallel in the close proximity specified, and whose peripheries are formed of a series of plane surfaces, any two of those which are adjacent being at an obtuse angle to each other, as shown and described.
